How long does this typically take to take effect?

How long does this typically take to take effect? I did this 1-2 hours ago and when I fill out the form it's still showing the thank you page, not a redirect.

Please note that the form shall be saved automatically as soon as the changes made to the form. As I check your JotForm, I see that the web page is set in the Thank you page to redirect. However, I also notice that there are 2 conditions set on the form to display the Thank you page.

If the form is not redirecting to the web page, these conditions may be overriding based on the data entered to the form and displaying the message. You may disable the conditions so that the form should be redirecting to the web page after submitting the form. 

If you need to redirect the form to the web page based on a condition, you may try setting up the conditions by following the guide below:
